LangShop theme is a template that duplicates the original theme. It gives Shopify merchants the extended abilities to translate all data in the online store like static text, resource tags, and images.
LangShop theme is optional. You can add language and currency selectors, recommendation banners, translate products, collections, pages, blogs, theme settings, locale files, dynamics in the original theme.
LangShop theme may also serve as a backup. If you accidentally delete the original theme, you can restore the translated one to its original state.
